knitr::include_graphics("lose_yourself_tempogram.png")In this tempogram you can clearly recognize 4 different parts of the song: - The first thirty seconds of this song are a piano intro. - Then from the thirty seconds the beat starts, which is clearly visible in the tempogram by an increase in the BPM. - From second 53 to 278 Eminem raps over the beat. You can see this in the tempogram as the blurring of what the exact BPM is. However, the computer still manages to find a reasonably straight line. - After second 278 the outro of the song starts with the beat extending for another 42 seconds. The start of the outro is clearly visible by the BPM line becoming brighter again.
A few things I still want to improve: - Computer was very slow, so I used window_size = 4 and hop_size = 1 for this tempogram. I want to add a sharper version for the final portfolio. - I also want to add a tempogram for the other two outliers of my corpus (Campaign Speech & Jimmy, Brian and Mike).
Looking at this chart, most New Eminem songs have a C# major (D flat major) key, and most Old Eminem songs have an E minor key.
The different keys in which a song can be played also bring different emotions. Emotions often associated with the D flat major key are “Grief & Depressive”. For an E minor key, the emotions are often “Effeminate, Amorous, Restless”. The emotions that New Eminem tries to convey in his music seem to match the emotions associated with the D flat major key. His music has become more and more about sad and political events in the world and about mental problems. Old Eminem’s songs were a lot more playful and upbeat; he had many songs about his daughter and wife, drugs and the rap game that often conveyed a somewhat insecure but positive mood (although certainly not always positive). These emotions do not correspond directly to the associated emotions of an E minor key, but are close.
A few things I still want to improve on this graph: - The y-axis now shows the count of songs. I want to make this a percentage. There are a lot more New Eminem songs than Old Eminem.
